The present disclosure generally relates to photographic equipments
field, and especially relates to a soft box.
2. Description of Related Art
In our daily life, mobile phones or cameras are often used to
photograph subjects. Because of the reflection or other reasons,
the quality of the picture which is taken is not very good, the
shadow of the subject, even the shadow of the photographer itself,
is appeared in the picture, thereby affecting the overall visual
effect of the picture. Even if the professional photographers
photograph in an empty space, the best picture with high quality
and clear color tones can't be obtained under the influence of the
shadow.
In order to obtain bright and clear pictures, a flash lamp is
usually used in a photograph device to provide an auxiliary light
source. A conventional flash lamp is provided by two installation
forms that either at the inner or the outer part of the camera. In
this way, such flash lamp located at the outer part of the camera
is divided into two usage modes: one usage mode is to shine the
light from the flash lamp directly on the subject, the other usage
mode is to combine the flash lamp with a soft box to diffuse the
light. During usage of the soft box, the light from the flash lamp
is separated according to the shape of the soft box so that the
texture and color of the subject being photographed can be same as
that in natural light. Thus, the soft box is widely favored by the
majority of users.

221 to threadedly connect with the limiting screw 232 in order to
limit the rotation of the turntable 22, which is more simple
structure. That is to say, the limit structure of the present
disclosure can be flexibly changed according to actual production
demands.
As another further improvement of the present embodiment, a wear
washer 4 is formed between the installing base 11 and each of two
opposite sides of the turntable 22. One side of the wear washer 4
is tightly fixed with the inner side of the installing base 11, and
the other side of the wear washer 4 is tightly fixed with the
turntable 22. The wear washer 4 is connected between two sides of
the turntable 22 and the installing base 11, thereby the turntable
22 is tightly fixed with the installing base 11. At the same time,
when the turntable 22 is rotated relative to the installing base
11, the relative friction of connection joint between the turntable
22 and the installing base 11 is mainly sustained by the wear
washer 4, which can better protect the housing 1 and the main body
for the lamp holder 2. Even when the joint between the turntable 22
and the installing base 11 is damaged, it just only needs change
the wear washer 4, thereby maintenance cost can be saved.
Furthermore, the turntable 22 includes a gear teeth 222 formed on
the outer side thereof, and a rack 41 is formed on a side of the
wear washer 4 close to the gear teeth 222. The installing base 11
includes a vertical slot 111, and a tenon 42 is formed on a side of
the wear washer 4 close to the vertical slot 111. The rack 41 is
engaged with the gear teeth 222 and the tenon 42 is inserted into
the vertical slot 111. The wear washer 4 can be more closely
engaged with the installing base 11 via meshing the rack 41 with
the gear teeth 222, which can reduce slip during in the turning
process. The wear washer 4 can be tightly fixed with the installing
base 11 by inserting the tenon 42 into the vertical slot 111, which
is simple and not easy to slip.
Specifically, the connection way of two sides of the wear washer 4
can be flexibly changed. For example, one side of the wear washer 4
meshes with the turntable 22, and the other side also uses a
meshing structure to mesh with the inner side of the installing
base 11. In this way, both sides of the wear washer 4 include the
meshing structure, thereby the stronger connection stability of
both sides of the wear washer 4 is ensured. Of course, both sides
of the wear washer 4 use the fixed structure that the tenon 42 and
the vertical slot 111 are cooperated with each other, which is more
convenient to assemble.
More specifically, the outer edge of the tenon 42 is arc-shaped,
the inner edge of the vertical slot 111 includes a corresponding
cambered surface to engage with the outer edge of the tenon 42, and
the top edge of the tenon 42 includes a guiding surface. In this
way, when the tenon 42 inserting into the vertical slot 111, the
tenon 42 is first entered the vertical slot 111 from the guiding
surface because it can be more easily inserted. Secondly, the tenon
42 slides on their contacting surfaces relative to the vertical
slot 111 until the tenon 42 sides into the vertical slot 111. The
tenon 42 is easier to slide in the vertical slot 111 because the
contacting surface between the tenon 42 and the vertical slot 111
is curved, thereby the faster assembly is completed. Meanwhile, the
tenon 42 is not easy to transversely get out of the vertical slot
111, thereby the fastness of the connection is ensured.
Preferably, the wear washer 4 includes a first wear washer 44 and a
second wear washer 45. The first wear washer 44 is formed on the
side of the main body for the lamp holder 2 close to the bolt 310,
and the second wear washer 45 is formed on the side of the main
body for the lamp holder 2 close to the handle 320.
Preferably, the installing base 11 includes a mounting hole 112,
the main body for the lamp holder 2 includes a connecting hole 24
corresponding to the mounting hole 112, and the wear washer 4
includes a center hole 43 corresponding to the mounting hole 112
and the connecting hole 24. The bolt 310 passes through the center
hole 43, the mounting hole 112 and the connecting hole 24 in turn
to threadedly engage with the threaded hole 321.
Preferably, a plain washer 5 is formed between the handle 320 and
the outer side of the installing base 11, thereby the outer side of
the installing base 11 can't be damaged by the outer side of the
handle 320.
As another further improvement of the present embodiment, the soft
box further includes an adjusting bolt 18 threadedly connecting
with the pressing plate 16 to limit the position of the press plate
16 relative to the supporting platform 17 by means of adjusting the
adjusting bolt 18. The light passageway 14 has a shape of square

annular disc 120 is formed on the radial peripheral of the annular
column hole 12. Each mounting groove 13 is L-shaped configuration
and includes an axial groove 131 and a radial groove 132. The axis
of the annular column hole 12 is coincided with the central line of
the light passageway 14. An axial locating end face 15 is formed
between the pressing plate 16 and the annular column hole 12.
The L-shaped structure is provided to greatly reduce the whole
volume of the soft box and improve high portability. In addition,
because of this L-shaped structure, the whole product can be molded
by the plastic injection molding, and then it can be obtained after
simple assembly, which can greatly save the manpower and cost.
Furthermore, the technical proposal of the present disclosure can
optionally adjust the connection position before and after between
the flash lamp holder and the soft box. At the same time, it can
ensure that the center of the flash lamp holder is located on the
central axis of the light passageway to achieve high light
transmission, which the two conventional types snap-fitting members
can't be realized. In the preferred proposal of the present
disclosure, the soft box integrates the chuck with the fastening
ring of the related art in essence through setting the annular
disc. In this way, the set-top flash lamp can be used
simultaneously with a set-top flash foldable soft box and a strobe
